The effect of replacing soybean crude protein (CP) with legume leaf meal (LLM) CP on feed intake, growth performance and carcass traits was studied in native female Moo Lath Lao pigs. The diets comprised one traditional diet (T) without soybean meal, one control diet (C) with soybean meal and six diets iso-nitrogenous with diet C in which soybean protein was replaced (33, 66 and 100 % of CP) with LLM CP from porcupine joint vetch (PLM) or Stylosanthes (SLM). Feed and water were offered ad libitum. Replacing soybean CP with LLM CP reduced (P?<?0.05) intake of dry matter (DMI), CP (CPI), metabolisable energy (MEI), final body weight (BW) and average daily gain (ADG), but had no effect (P?>?0.05) on feed conversion ratio (FCR). Increasing the replacement rate of soybean CP with LLM CP had a negative linear effect (P?<?0.001) on DMI, CPI, MEI, final BW and ADG, and on all carcass traits except lean meat percentage. There were no differences in dressing percentage or organ weight and length between treatments. Supplementing diet T with soybean meal resulted in higher (P?<?0.05) DMI, CPI and MEI, lower (P?<?0.05) FCR, and higher (P?<?0.05) final BW and ADG. Slaughter weight, hot carcass weight, eye muscle thickness, back fat, fat in carcass and lean meat were lower (P?<?0.05) with diet T than diet C. In conclusion, LLM from stylo and porcupine joint vetch can be used as a CP source to partially replace soybean meal CP in the diet of growing native female Moo Lath Lao pigs. 相似文献

Feeding and performance of pigs in smallholder production systems in Northern Lao PDR 总被引:1,自引:1,他引:0

A survey was carried out in the North of Lao PDR to study feeding systems and the performance of pigs in smallholder systems.
A total of 341 farmers from five provinces were interviewed. To feed their pigs, farmers mainly rely on feedstuffs produced
on the farm and collected from areas near the village. The feedstuffs used included by-products such as rice bran and distiller’s
waste, planted feeds, mainly maize and cassava, and various green plant materials. The feedstuffs used are usually high in
energy and low in protein content, and the only readily available protein source is green plant material. This results in
nutritionally imbalanced diets and as a result poor pig performance. The average growth rate of pigs in these systems was
found to be only approximately 100 g/day. The reproductive performance of sows was found to be relatively low, as is the case
of local breeds in the region, with an average litter size at birth of 6.8 piglets. The mortality of piglets was as high as
50% and was a main concern of farmers. In order to improve the productivity of pigs in smallholder systems, there is a need
to find alternative feed resources to improve the nutritional feed quality, and to develop management systems which are suited
to the needs and practices of smallholders. 相似文献
